Application
四氯钯酸钾(II)可用于：
- 作为前体 合成用于催化降解有机污染物的Pd纳米颗粒， 以及用于甲酸和乙醇氧化的Pd-GO电催化剂。
- 以均匀的Pd八面体纳米晶和立方纳米晶（NC）为牺牲模板，采用电偶置换法合成具有空心结构的Pd–Pt 合金 NC。中空NC的ORR活性更高。
- 合成 固定化Pd催化剂，这种通用方法是 将PAA和PEI-Pd(II)逐层沉积在氧化铝上，然后还原 Pd2+。这种方法有几个好处， 包括通过聚电解质基质稳定颗粒、引入选择性 以及显著减少不必要的异构化。扩大聚电解质薄膜的应用有望进一步提高 加氢反应和 其他反应的选择性。
- 制备用于气敏应用的导电性多孔金属有机骨架（MOF）， 还可在金属有机骨架（MOF）上 合成双金属 Pd/SnO2纳米颗粒，作为乙醇氧化的 电催化剂。
- 制备具有多芳烃配体 的刚性大环钳形催化剂，催化 活性更强。
Features and Benefits
用于合成半导电的含金属聚合物，在聚合物中聚吡咯主链具有最低的构象能，并且几乎成平面。与双二硫醇盐反应生成金属-双二硫醇盐，可用于激光器 Q 开关材料、光盘记录介质、条形码材料和超导体。

For patch testing, replacement of the commonly used palladium dichloride (PdCl2) by sodium tetrachloropalladate (Na2[PdCl4]) was recently demonstrated to improve test accuracy and show a significant correlation with nickel (Ni), supporting the concept of cross-reactivity between Pd and Ni. A

The interactions of potassium tetrachloropalladate(II) with the B6 vitamins pyridoxal, pyridoxine, and pyridoxamine in 1:1 molar ratio have been studied. From DMF solutions, the ionic trichloro (pyridoxal or pyridoxine) palladates(II) were isolated. Pyridoxamine, on the other hand, in aqueous solutions
